我在我的应用程序中实现了一个回收站 View 来显示公司中的人员列表。我将所有这些信息存储在 Realm DB 中。现在我想在窗口顶部实现搜索选项，以便用户可以按姓名搜索人。我尝试使用以下代码。但是这个功能不起作用。我无法在此窗口上进行任何搜索。这是我的 recyclerView searchView 代码。
我的 Activity 课
public class MyColleaguesPage extends AppCompatActivity implements MyColleaguesAdapter.ColleagueListListener{
private RecyclerView recyclerView;
private MyColleaguesAdapter adapter;
private Realm colleagueRealm;
private RealmResults<MyColleagueModel> colleagueResult;
private List<MyColleagueModel> filteredModelList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mycolleagues_layout);
}
colleagueRealm = Realm.getDefaultInstance();
recyclerView = (RecyclerView) findViewById(R.id.colleagues_recycler);
if (!Prefs.with(this).getPreLoadColleague()) {
setRealmData();
}
setUpRecycler();
showAllPersons();
}
private void showAllPersons() {
colleagueResult = colleagueRealm.where(MyColleagueModel.class).findAll();
setAdapter(colleagueResult);
adapter.notifyDataSetChanged();
}
private void setAdapter(RealmResults<MyColleagueModel> results) {
adapter = new MyColleaguesAdapter(this, colleagueRealm.where(MyColleagueModel.class).findAllSortedAsync("id"),this);
recyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
private void setUpRecycler() {
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
recyclerView.setHasFixedSize(true);
// use a linear layout manager since the cards are vertically scrollable
final LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
}
private void setRealmData(){
.......
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.recycler_menu, menu);

filteredModelList = filter(colleagueResult, newText);

} else {
Toast.makeText(MyColleaguesPage.this, "Not Found", Toast.LENGTH_SHORT).show();
return false;
}

});
}
private List<MyColleagueModel> filter(List<MyColleagueModel> models, String query) {

我的适配器类
public class MyColleaguesAdapter extends RealmRecyclerViewAdapter<MyColleagueModel, MyColleaguesAdapter.ColleagueHolder>{
private List<MyColleagueModel> myColleagueModels;
private Context context;

public MyColleaguesAdapter(ColleagueListListener colleagueListListener, RealmResults<MyColleagueModel> realmResults, Context context ) {
super(realmResults, true);
this.context = context;
this.colleagueListListener = colleagueListListener;
}
// create new views (invoked by the layout manager)
@Override
public ColleagueHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//inflate a new colleague view
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.colleage_row_layout,parent,false);
return new ColleagueHolder(view);
}
@Override
public void onBindViewHolder(ColleagueHolder holder, int position) {
final MyColleagueModel myColleague = getData().get(position);
//final MyColleagueModel myColleague=realmResults.get(position);
holder.colleagueName.setText(myColleague.getName());
holder.companyName.setText(myColleague.getCompany());
holder.jobTitle.setText(myColleague.getTitle());
holder.cardView.setTag(position);
holder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//editDataInterface.editData(view,position);
int pos = (int)view.getTag();
Intent i=new Intent(context,DetailMyColleague.class);
i.putExtra("name",myColleague.getName());
i.putExtra("title",myColleague.getTitle());
i.putExtra("company",myColleague.getCompany());
context.startActivity(i);
}
});
}
public class ColleagueHolder extends RecyclerView.ViewHolder{
.......
